ROBERT NioironAsiviUnrHY, or OTTAWA, ONTARIO, CANADA.

MsANI'TARY Be it known that l, ROBERT 4NICHOLAS MURPHY, a subject of tthe/King of Great Britain,y and resident' of the city of Ottawa, in the*ProvincejsoOntar1o,fDOm1nion of Canada, have invented certain new and useful vImprovements in ySanitaryV Traps,` `of whichrthe following is a speciiication.

'the invention lconsists essentially of thefimroved construction. particularly described and set orth in t 'e `following specification and accompanying drawings forming part of thesame. 1' l p 'f Figure '1 1 is fa side 'elevation` of th@J :tmp

The curvilinear pipe 12 is provided with an upwardly extending Ventilating pipe 111, while on one sidea laterally extending boss 15 is formed with which the nut 16 makes threaded engagement.

' Application ledMarch 18, 1918. Serial No. 223,161. i

A flushing. cockV 17 is rotatably mounted the inner end of the cock against formed with a hexagonal outer wall 19 de- 1 signed to be engaged with a spanner to permit of Vthesaid `cock being manually rotated.. The outer end-20 of the `cock is threaded so that' it may be readily connectedto a hose or like `flexible pipe whichm turn is convnected toia water main or faucet.`

The flushing. cock 17 isV formed with a .hollowbore21 terminating adjacentto the .Qhemispherical end of the Vcock and this bore communicates with an outlet yorifice 22 extendingthrough the wall of the cock.`

Ast-he cock ,17 is rotated, the oriiice 22 willgriegister'with the'bore of eitheroi' `the -wat'erfseals 10 and 111 or with vtheventilating :pipe 14 so .that each-Oi1 these parts of the Whenfthe trap is normally in use, the Y flushing cock-.17 willv not be positioned as the outerl aceof the boss 15 and the nut 16. the seals 10 in Fig.` 1 and thismethod might be adapted where a'suliicient clearance is obtained between the Wall 0f the room where the fixture In this manner the lnut 16 is readily accessible to permitlof theflushing cock 17 being inserted inter the boss 115 ifit is found desirable to .-Normally thecurvilinear pipe 12 would vform an air chamber between the seal 10 vor 11 but'should the Ventilating pipe 14 become the seals l or I1l,

\ be adjusted relatively to each` being inserted into the boss 15, whereupon the nut 1G will be replaced and the flushing cock connected to a water main.

The flushing cock is now rotated into that position shown in Fig. 4, in which the orifice 22 registers` with the Ventilating pipe 14, and when thef pressure i'v the water from" the main is exerted on the blockage inthe-'said Ventilating pipe, the said blockage will. be forcibly removed or blown out. t

Should any blockage occur in =either=of the flushing cock 117fmay be rotated until the discharge oriiceA 22A registers with the bore of the said sealsfand the water from the water'main can-'then be turned into the said seals to thoroughlyush and clean thesame out. The flushing of the trap will thus occupy at the most,'only^a few minutes. l

If it is found :that the clearance between the liXture and the `wall of the room .in-"which it is placed is not Very great, then the seals 10 and 11 can be arranged in parallel planes, and 'the curvilinear 1 pipe 12' arranged. transversely to the seals, but connected lvthereto by means of the nut 13, and-in .this position the trap will only occupy about two-thirds of the space occupied in that positic'mv shown in Fig. 1.

If the space between the Awall, and the iX- ture is even nioreflimited, thewater'rseals '10 and 11 can bearranged iii/parallel planes asshown in'Fig. 3 when the curvilinear pipe 12 is transversely arranged relatively tothe seals and in this position'the trapV will only occupy one-half of the space shown infFig. 1.

There are an indefinite :number oflangles andpositions inwhich the seals 10rand `1l can be arranged `:relatively-to each other, and the curvilinear pipe12canrbeinterchanged to bring the-boss 15xint0't`he desired position to give azready access thereto for the insertion of the flushing cock 17.

From the above description, `it will be seen that I have invented an adjustable trap capable of being used on all fixtures at: present in use, and in which the water seals can other, :and to a connecting air chamber located therebetween, so that when the trap lis arranged in position it will be conipactiin construca fwidelyidiferent' embodiments ltion within :the scope of ,the claims, constructed without rand provided, with tion and occupy a minimum or' space, yet permitting at alltimes that the several parts wi l' be' capable freadyinspection or being fiushed should a blockage occur. y

It should also be particularly borne in mind that ,the flushing cock 17 while adapted for" flushing out blockage in thetrap may Valso befused ,-forfapplying an ordinary gas or smoke test when such is found necessary by sanitary engineers orin compliance .with any municipal regulations.

.As many. changesy coruldbe madeninthe above construction fand many apparently ofmy invendeparting `from the spirit or scopel thereof, it is intended-that all matter contained inthe accompanying specifi- :cationl andi drawings shallV beit-interpreted as illustrative and-:not :inl ya limiting sense.
